Quick answer

Our top pick is the Kurgo Step & Strobe Waterproof Dog Raincoat for its excellent waterproofing, reflective trim, and secure fit for small dogs. If you need a budget-friendly option, the Rabbitgoo Dog Raincoat offers great value with a hood and leash hole. For maximum visibility in low light, the Ruffwear Sun Shower Raincoat features bright colors and reflective accents.

What to consider for Dog Raincoat For Dogs Under 20 Lbs

Small dogs have unique needs when it comes to raincoats. A proper fit is crucial: the coat should cover the back and belly without restricting leg movement or dragging on the ground. Look for adjustable closures like Velcro straps or snap buttons to customize the fit. Waterproof and breathable fabrics (e.g., nylon with a polyurethane coating) keep your dog dry without overheating. Reflective elements are important for visibility during gloomy weather. Also consider a leash hole on the back for easy attachment, and a hood that stays put without blocking vision.

What to look for in a gear item (harness, collar, leash or muzzle)

For a raincoat, focus on correct fit and sizing: measure your dog’s back length and chest girth, and compare to the brand’s size chart. Durable hardware like rust-resistant zippers and strong Velcro ensures longevity. Safety features include reflective piping or strips for low-light walks, and a design that won’t choke or restrict breathing. Comfort and padding are important: look for soft inner linings and non-abrasive seams. A no-pull design isn’t typically a factor for raincoats, but a well-fitted coat should not impede movement or cause your dog to overheat.

How we chose these picks

  • Evaluated product descriptions and customer reviews for waterproofing claims and real-world performance.
  • Checked sizing options to ensure availability for dogs under 20 lbs (back length 10 to 16 inches).
  • Prioritized coats with reflective elements for safety in low light.
  • Considered ease of putting on and taking off, including adjustable closures.
  • Assessed material quality: waterproof, breathable, and durable fabrics.
  • Looked for practical features like leash holes, hoods, and storage pockets.
  • Compared price points to offer options for different budgets.
  • Never ranked a product higher just because it pays a commission.

What to avoid

  • Avoid raincoats that are too tight or too loose; ill-fitting coats can chafe or trip your dog.
  • Steer clear of flimsy materials that tear easily or have weak seams that leak.
  • Do not use a raincoat with a built-in harness unless it fits perfectly and doesn’t restrict movement.
  • Avoid coats with long hoods that obstruct peripheral vision or cause anxiety.
